LIQUID DISPENSING.

Application filed December 3, 1928. Serial Nd 323,41LRESSUED Thisinvention relates (particularly, though not exclusively, to the eliveryof gasolene and the like.

Special objects of the invention are to provide apparatus for thepurpose, which will be simple, safe, positive and operable to accuratelyand speedily deliver various required amounts of the liquid.

Further objects of the invention are to enable the delivery bcinentirely controlled at the discharge end of tie apparatus.

The foregoing and other desirable objects are attained by the novelfeatures of construction, combination and relation of parts,hereina't'ter described and illustrated by way of example in theaccompanying drawings.

In the drawings, Fig. 1 is a broken side view of the discharge hose endof a gasoline delivery system having features of the inventionincorporated therein; Fig. 2 is an enlarged and broken sectional viewillustrating details of the nozzle valve and Bowden wire control; Fig. 3isa smaller view similar to Fig. 1 illustrating a construction in whichthe Bowden wire control is contained entire- 1y within the hose; Fig. 4is a view of the combination delivery valve and electric switch, theformer governing flow to the hose and the latter controlling an electricpump 3 or valve governing flow in the delivery line;

Figs. 5, 6 and 7 are broken sectional views illustrating the timedrelation of the valve and switch; Fig. 8 is an enlarged cross-sectionalview of the hose showing the weaving of the Bowden wire into the bodystructure of the hose; Figs. 9 and 10 are broken detail viewsillustrating modifications in which operation of the controls iseifected by simply pulling on the hose; Fig. 11 is a broken partsectional view showing the invention applied to an air pressure systemof delivery.

In Fig. 1 a delivery or supply line is indicated at 12 having a deliveryvalve 13 therein. .a-nd terminating in a flexible discharge hose 14ending in a suitable discharge nozzle 15.

The. liquid to be delivered is furnished the delivery line from asuitable supply, such as a storage tank and an electrically driven pumpas in Fig. 4 of Patent 1,685,036 or from a pressure tank as in Fig. 5 ofthe same patent, or as in Fig. 11 of this case from a tank 16 from whichthe liquid is expelled bycompressed air. v The delivery valve 13 isshown i'n Fig. 1

as of the rotary plugtype, but it should be understood that other formsof valves may be employed, the one illustrated being convenient andsuitable for the purpose, providing as it does a shaft 17 by which itmay be operated and which may be coupled as indicated at 18 in Fig. 4 tooperate an electric controlling switch 19.

The final delivery is shown as controlled. by a valve 20 operating in avalve casing 21 in the nozzle and having a projecting stem 22 engaged bya valve opening hand lever 23 pivoted on the nozzle at 24. v

The movement of the nozzle valve hand lever 23 is utilized to effect theoperation of the delivery valve and control switch through the medium ofa Bowden wire flexible mechanical connection 25 engaged with anextension 26 of the hand lever and extending along the hose through atubular guard or cover 26 to one arm of the bell crank lever 27 on theend of delivery valve shaft-17.. The other arm of this bell crank leveris shown engaged by a valve closing spring 28 which is heavy enough toclose the delivery valve and also to pull the Bowden wire back throughits flexible sheath when the grip on the hand lever is released.

A rigid guide 29 is shown formed on the side of the nozzle structure forthe lower end of the Bowden wire, directing the same in a substantiallystraight line to the lever 26, which is shown doubled in under the valvecasing, to shorten the exposed length of wire. For adjustment purposes,the end of the wire is shown as having a turn-buckle connection in theform of a rotatable member 30 having a screw engagement in the angledend 31 of the lever 26 and secured in its position of adjustment by locknut 32.

Another special feature of the Bowden wire connection thus far describedis that the sheath of the same is built into the structure of the hose,so as to be in effect an integral part of the same. This is shown asaccom- 10o plished in Fig. 8 by encasing the sheath in between the innerand outer layers 33, 34 of the braided or woven outer covers of thehose. In practise, the hose may be made up with the inside cover and theoutside cover 106 be then applied so as to encompass and incorporate theBowden wire within the hose structure. Eneircling clamps 35 are shownapplied about the end portions of the hose, said clamps being set uptight by screws 36 110 and fitted at 37 to grip the bulge of the Bowdenwire, so as to hold the latter against tendencies to twist or spiral inthe hose. The Bowden wire is thus by its incorporation in the hose andby means of the end guide and clamps held in substantially parallelrelation wifih the axis of the hose so that the length f the wire willnot be varied to any objectionable extent by the bending or twisting ofthe hose.

Another way of incorporating the Bowden Wire into the hose isillustrated in Fig. 3. In this case, the Bowden wire designated 25 isplaced inside the hose, being shown as spiraled so as to lay against theinside wall of the hose and to accommodate itself to the bending of thehose without objectionably varying in length, the sheath 26 of the wirebeing suitably held in the end fittings of the hose as indicated by theclips 38. In this case, inside connections can be made at both ends ofthe Bowden wire. Thus, atthe nozzle end the wire is shown connected withone arm of a bell crank lever 39 mounted in the nozzle valve casing 2 1in position with its other arm beneath the lower end of the "alve stem22* so that each, time the hand lever 23 is operated, the opening of thevalve will effect a pull on the Bowden wire. At the opposite end thewire is connected with the valve lever 27 within the casing 13 of thisvalve, which for the purpose is made to enclose the valve operatinglever as indicated at 40.

The fully enclosed type of Bowden wire control shown in Fig. 3 hascertain advantages, particularly as regards the enclosure and mechanicalprotection of the Bowden wire and its connections.

Instead of incorporating a Bowden wire in the hose, the hose itself maybe ut'lized as a form of flexible mechanical connection for operatingthe delivery valve mechanism. Thus as shown in Fig. 9,,an extensible ortelescopic section such as the sylphon orzbors rugated metallic bellows41 may be interposed as a section of the hose length permittingexpansion or extension of the hose and a part of the hose beyond orbelow such extensible portion, such aswthe collar 42 be connected withthe valve lever 27 b by. means of a link 43. This bellows section isshown telescopically secured over an extension sleeve 44 of the valvehead IS -and the valve closing spring 28 is made strong enough in thisinstance to effect both closing of the valve and the collapsing movementof the hose section when pull on the hose is released.

. In another embodiment of this hose pull delivery valve, shown in Fig.10, the link 43 connected with the valve lever, is-engaged with a collaror loop 45, or otherwise hooked about the down-hanging upper end portion14 of the hose, so that an outer pull on the hose in the direction ofvthe arrow will open the valve. In this case, also the valve closingspring 28 effects a retraetive movement of the hose enabling theoperator to controlthe delivery valve entirely by pulling or releasingpull on the hose. This last construction, it may be observed, may beapplied to existing filling stands.

Stops indicated at 46 may be provided to limit the valve opening andclosing movements and also the extensive and retractive movements ofthehose.

The delivery valve and the switch which controls the supply of liquidinto the delivery line may have a timed relation such that the liquidwill be started into the line before the valve opens, so as to bereadylfor instant delivery the moment the valve permits, and such thatthe valve will close before the switch is thrown off, to make sure thatthe delivery of liquid will be fully completed. This timed relation ofvalve and switch is illustrated in Figs. 5, 6 and 7, and as there shownis accomplished by making the coupling 18 between valve stem and switchas a lost motion connection by which the switch is thrown on before thevalve opens and thrown off after the valve closes -see par ticularlyFigs. 5 and 7. y

The Bowden wire or pull hose mechanical controls may be applied to airpressure -or other forms of deliyery systems. For

example, an air pressure delivery system is illustrated in Fig. 11 inwhich the Bowden wire is utilized, the compressed air being there shownas supplied from a tank 47 through pipe 48 and b way of valve 49 and apressure line 50 to t 1e top of the pressure tank 16, which receivesliquid from a storage tank by gravity and check-valve or otherwise, theliquid flowing from this tank by delivery line 12, governed by theBowden wire control, which in this case operates both the air valve 49and the special delivery valve 51,. For operating both these valves, theBowden wire is shown connected with a triple. armed bell crank 52 havingone arm engaged with the stem 53 of the air valve and the extra or thirdarm connected by pull link 54 with lever 55 bearing on the stem 56 ofthe deli-very valve.

This delivery valve is shown as ofa special push type in which the stem56 is sealed tight in a leak-preventing sylphon 57 The inner end of thisstem is shown as carrying a valve 58, which can close against a seat 58in the end of the hollow sliding valve body 60 after it has pushed inthe valve stem 61 sliding in the bore of the tubular valve body. Valvestem 61 carries a spring pressed valve 62 seating in the opposite end ofthe sliding valve body 60, so that in this first part of the movementvalve 58 opens valve (32 admitting liquid under pressure in the deliveryline to the back end of the sliding valve body 60, balancing the latterso as to reduce the force required to shift this main valve from itsseat 63. This lost motion arrangement thus effects first the valving ofpressure behind the main delivery valve and then the opemng of said maindelivery valve.

Passages 64 are shown about the stem oj thestartihg valve 58 admittingliquid from liquid then serves in effect as a. hydraulic piston, asvalve 58. seats -in the end of the main valve 60 aiding in transmissionof the opening movement to said main valve 60. As the main valve opens,-the liquid in the delivery line flows on through the meter 65 and outthe hose under control at all times of the nozgzle valve 21.

Theair valve at 49 is shown as of the pressure-relief type involving anextra reversely faced valve element 66 on the valve stem 53 closingagainst seat 67 to shut ofl' the vent line 68. hen the valve at 49opens, an opening to .vent air pressure back through the pressure line50 .from tank 16 when delivery is completed and the valve at 49 closes.

The Bowden wire control in the case last described thus effects a tandemoperation of pressure supply valve mechanism and delivery valvemechanism, and it will be plain from the disclosure that the same may beapplied to other types or forms of dispensing apparatus;

As the Bowden wire is incorporated within and anchored in the flexiblehose, it is in effect a unitary portion of the hose, adding noappreciable bulk or projections on the hose,-flexing freely with thehose and operating in all the different positions of the hose.

Theinc'orporation of this Bowden wire in the hose also providesmechanical protection for the Bowden wire assuring proper operation ofthe same even under conditions of abuse. In order that the entirecontrol mechanism may be locked when not in use, a padlock is indicatedat 69 in Fig. 1, having its hasp passed through aligning openings in astationary lug 7 0 on top of the nozzle and a looking lug 71 on theunder side of the hand grip. Thisarrangement locks the hand grip andthrough that the nozzle valve, the flexible operating connections andthe control mechanism at the head or entry end of the hose. The locationof the hand grip on top of the nozzle and the extension of the. part 26below or to the underside of the nozzle forms a compact, convenient andeasily operating structure.
